how to define List of LogicalExpressions in query Record

Hm ... what exactly is your question? In Appian, we create lists using curly brackets {}.

As per the documentation  we can provide only a single logical expression or a list of query filters.

But I have a requirement 

a!queryRecordType(
recordType: RecordName,
fields: {},
filters: a!forEach(
items: ruleInput,
expression: a!queryLogicalExpression(
operator: fv!item.gate,
filters: {
a!queryFilter(),
a!queryFilter(),
a!queryFilter()
}

True, but a logical expression can take a list of logical expressions.

docs.appian.com/.../fnc_system_a_querylogicalexpression.html

I am getting an error 
Expression evaluation error at function a!queryRecordType [line 6]: Query has an invalid value for "filters". Filters can only be a list of a!queryFilter() or a single a!queryLogicalExpression(). Received: List of LogicalExpression.

Could you please help me with same code to configure.

Thanks in Advance

I think it's possible to configure a list of logical expressions within the query entity function, rather than within the query record type function.

Thanks for your input but I need this only on query Record

Or you can try the below logic:

a!queryRecordType(
  recordType: "RecordName",
  fields: {},
  filters: a!queryLogicalExpression(
    operator: "AND / OR / AND_ALL",
    logicalExpressions: a!forEach(
      items: "ruleInput",
      expression: a!queryLogicalExpression(operator: fv!item.operator, filters: {})
    )
  )
)

Thanks I have tried this and getting expected results.
